中文摘要:
      针对目前纸箱印刷机送纸机构普遍采用拉纸辊结构,存在破坏纸板强度的缺点,笔者提出了基于取消拉纸辊的无压损送纸机构的控制方法。分析了无压损送纸机构的特点,设计了双机械凸轮结构;根据机械凸轮的结构参数及送纸轮与格栅板凸轮的运动规律计算出各运动轴运动曲线的坐标参数;采用伺服运动器拟合设计出各运动轴最优的电子凸轮运行曲线;设计了该机构基于伺服控制与PLC技术的控制系统,包含上位机控制系统以及现场控制系统。应用结果表明:该控制方法在取消拉纸辊对纸板的拉力情况下,仍能保证甚至提升送纸精度;避免因纸板受挤压而强度降低,最大限度提供纸板传送动力。该方法为解决纸板损伤问题提供了实例。
英文摘要:
      In response to the problem of strength reduced by construction of pull roll that widely used in printing machine, a control method of non crushed feeding based on the feeding unit without pull roll was proposed. The character of non crushed feeding mechanism was analyzed. A construction of double mechanical cam was designed. Coordinate parameters of motion curves for each motion axis were calculated according to the structural parameters of the mechanical cam and the motion law of feeding wheel and cam of table plate. The optimal electronic cam curve for each motion axis was designed by fitting in servo motion controller. The control system including HMI PLC control and on site servo control based on the technology of servo motion control and PLC was proposed. It shows that this control method can guarantee or even improves the paper feeding accuracy without pull roll, avoiding the paperboard reducing its strength due to extrusion and providing cardboard transmission power to the maximum extent. This method provides an example for solving the damage problem of paperboard.
